摘要:
A biological tissue collection device is provided having a housing with a fluid-retaining inner chamber adapted to retain a bioimplantable, fluid permeable tissue scaffold. The scaffold is preferably retained in the housing in such a way that the scaffold separates the fluid-retaining inner chamber into a first chamber and a second chamber. The collection device further includes a driver mechanism coupled to the housing and effective to create a force within the housing to displace fluid disposed within the second chamber to the first chamber. As the fluid is displaced, any biological tissue deposited on the tissue scaffold is dispersed within the fluid. Removal of the force enables the fluid to return to the second chamber and thereby deposit the tissue onto the tissue scaffold. In an exemplary embodiment, the tissue is deposited evenly onto the tissue scaffold.

摘要:
A small diameter delivery device capable of delivering a tissue loaded scaffold arthroscopically to a tissue defect or injury site without reducing the pressure at the injury site is provided. The scaffold delivery device of the present invention comprises a plunger system that includes two main components: an insertion tube and an insertion rod. The insertion tube has a flared proximal end for holding a tissue scaffold prior to delivery. An elongate, hollow body extends from the flared proximal end to a distal end of the insertion tube, and defines a passageway that extends through the body for delivery of the tissue scaffold. The insertion rod has an elongate body that extends into a handle at a proximal end and a tip at a distal end. The insertion rod is configured to be removably disposed within the insertion tube for sliding along the passageway to effect delivery of the tissue scaffold through the insertion tube.

摘要:
A biocompatible tissue implant. The tissue implant may be bioabsorbable, and is made from a biocompatible polymeric foam. The tissue implant also includes a biocompatible reinforcement member. The polymeric foam and the reinforcement member are soluble in a common solvent.
摘要:
A biocompatible tissue repair stimulating implant or “scaffold” device is used to repair tissue injuries, particularly injuries to ligaments, tendons, and nerves. Such implants are especially useful in methods that involve surgical procedures to repair injuries to ligament, tendon, and nerve tissue in the hand and foot. The repair procedures may be conducted with implants that contain a biological component that assists in healing or tissue repair.

摘要:
A biocompatible tissue repair implant or scaffold device is provided for use in repairing a variety of tissue injuries, particularly injuries to cartilage, ligaments, tendons, and nerves. The repair procedures may be conducted with implants that contain a biological component that assists in healing or tissue repair. The biocompatible tissue repair implants include a biocompatible scaffold and particles of living tissue, such that the tissue and the scaffold become associated. The particles of living tissue contain one or more viable cells that can migrate from the tissue and populate the scaffold.
